Defined in header <bitset>
template< size_t N > class bitset;

Bitsets give the programmer a set of bits as a data structure. Bitsets can be manipulated by various binary operators such as logical AND, OR, and so on.

The size of a C++ bitset is fixed at compile-time, and the size is the template parameter to the bitset.

[edit] Member functions

(constructor)	constructs the bitset (public member function)
operator=	assigns the contents (public member function)
operator== operator!=	compares the contents (public member function)
Element access
operator[]	accesses specific bit (public member function)
test	accesses specific bit (public member function)
all any none	checks if all, any or none bits are set to true (public member function)
count	returns the number of bits set to true (public member function)
Capacity
size	returns the size number of bits that the bitset can hold (public member function)
Modifiers
operator&= operator|= operator^= operator~	performs binary AND, OR, XOR and NOT (public member function)
operator<<= operator>>= operator<< operator>>	performs binary shift left and shift right (public member function)
set	sets bits to true or given value (public member function)
reset	sets bits to false (public member function)
flip	toggles the values of bits (public member function)
Conversions
to_string	returns a string representation of the data (public member function)
to_ulong	returns an unsigned long integer representation of the data (public member function)
to_ullong (C++11)	returns an unsigned long long integer representation of the data (public member function)
